Week 5 - Probability
How are probabilities assigned to different events? This is a question we will see is not always so simple to answer. If we know the likelihoods for every possible event then we can study how the probabilities are distributed to the different possible outcomes. A probability distribution refers to either the table or graph of all possible likelihoods. Once this distribution is created we can see important overall patterns like determining if an investment is lucrative or what the average result from a random event will be.
- Learn the basic notation and terminology for probability
- Determine whether two events are mutually exclusive.
- Determine whether two events are independent.
- Calculate probabilities using the Addition Rules and Multiplication Rules.
- Construct and interpret Contingency Tables.
- Use contingency tables to evaluate and interpret conditional probabilities.
- The learner will calculate and interpret probabilities.
- The learner will use contingency tables to calculate false positive and false negative probabilities.

- Apply - Complete the Application Problems and upload your completed files.
If you have any questions about the content (readings, problems, etc.) then post in the "Questions about Week 5" forum.
The class will work together to create a wiki for the topic of probability. I will provide an outline and each of you will add at least one point (one or two complete sentences). Use the following guidelines
- Type your name in parentheses next to your contributions
- Try and keep it general.
- Check to make sure you are not repeating someone else.
- If you correct someone else, use strike-through (example) instead of deleting what they wrote.
- Put things in your own words, don't just copy from the book.
- Make sure you put your response in the right place, use my outline as the guide.
- Use correct symbols or formulas where necessary. The Math Symbols button is available for you to use.
